• About Philadelphia on February 220! of this year, the Winter 

 Aconite {Eranthis Jiyemalis) was opening- its pretty yellow flowers, 

 the first really conspicuous blossom of the year. On the same day, 

 in the low land along the Delaware just south of the city, the Silver 

 Maples {^Acer dasycarpujn) were sparingly in bloom on the southern 

 sides of the trees. In a sunny spot on the banks of the Schuylkill, on 

 March 6th, one plant of Spring Beauty (Claytonia Virginica^ had 

 ventured a shy blossom into the winds of March, while a couple of 

 buds showed pink, apparently waiting the result of the pioneer effort 

 of their sister. Hard by, the crevices of the rocks sheltered from the 

 north and warmed by the afternoon sun, twinkled with the tiny white 

 blossoms of the Whitlow Grass {Draba verna). This last small har- 

 binger of the spring was discovered in bloom last year in the same 

 place as early as February 21st. — C. F. Saunders, Philadelphia, Pa.
